What happens to the body when the PH of the blood becomes too alkalotic?

Question

I know the body will compensate up to a certain point, but what happens to the body when it can't compensate any longer?

Answer 1

Well, alkalosis shifts the oxygen dissociation curve.
CO2 retention (hypoventilation) causes acidosis, breathing too much (hyperventilation) causes alkalosis. The kidneys will compensate, but the body will think it needs ot retain CO2 to offset this alkaline pH. Shallow breathing would result, kidney compensation would result. Obviously it couldn't go on forever, too much pH derangement will eventually kill you. I suppose it could lead to respiratory arrest. But alkalosis is not as common or severe as acidosis.
